Garcia threw rocks at her car as she drove away from the shop in the 200 block of Castroville Road, police said.

Officers sent to the shop told the Medrano family to call police again if Garcia returned.

Police said he came back about two hours later with Matamoros and a third man. Medrano was brutally beaten along with his son Joseph Medrano, 27.

When police arrived, the elder Medrano was on his back with a pool of blood around his head. Joseph Medrano was trying to stop the bleeding with a sheet.

The elder Medrano died about an hour later at University Hospital. Joseph Medrano was badly hurt but is expected to live.

Hinojosa led police to Garcia. Police found him at his apartment in the 300 bock of West Cheryl Drive lying on a bed next to two baseball bats. He had blood on his clothes and a swollen right hand, police said.

Police found Matamoros after he was identified by his cousin, who said she drove the suspects to the shop, not realizing an attack was planned.
